Protective effect of porphyra-334 on UVA-induced photoaging in human skin fibroblasts
The significant increase in life expectancy is closely related to the growing interest in the impact of aging on the function and appearance of the skin. Skin aging is influenced by several factors, and solar ultraviolet (UV) irradiation is considered one of the most important causes of skin photoaging. The aim of this study was to examine the anti-photoaging role of porphyra-334 from Porphyra ...
متن کاملPreventive effect of dietary astaxanthin on UVA-induced skin photoaging in hairless mice
Astaxanthin, a carotenoid found mainly in seafood, has potential clinical applications due to its antioxidant activity. In this study, we evaluated the effect of dietary astaxanthin derived from Haematococcus pluvialis on skin photoaging in UVA-irradiated hairless mice by assessing various parameters of photoaging. After chronic ultraviolet A (UVA) exposure, a significant increase in transepide...
متن کاملOrally administered Polypodium leucotomos extract decreases psoralen-UVA-induced phototoxicity, pigmentation, and damage of human skin.
BACKGROUND The use of psoralen-UVA (PUVA) in patients of skin phototype I to II is limited by side effects of acute phototoxicity and possible long-term carcinogenesis. OBJECTIVE We sought to assess oral Polypodium leucotomos (PL) extract in decreasing PUVA-induced phototoxicity of human skin on a clinical and histologic level. METHODS A total of 10 healthy patients with skin phototypes II ...
متن کاملUV-induced skin damage.
Solar radiation induces acute and chronic reactions in human and animal skin. Chronic repeated exposures are the primary cause of benign and malignant skin tumors, including malignant melanoma. Among types of solar radiation, ultraviolet B (290-320 nm) radiation is highly mutagenic and carcinogenic in animal experiments compared to ultraviolet A (320-400 nm) radiation. Epidemiological studies s...
متن کاملProstaglandins, Histamine and Platelet Activating Factor: Different Mediators in Dithranol-Induced Skin Damage
Dithranol is a potent agent in treating psoriasis but its adverse effects on intact skin have limited its usage. There are many proposed mediators for its adverse effects including prostaglandins, histamine, platelet activating factor and free radicals. In this study we examined the effect of different agents (diazepam, terfenadine, indomethacin and garlic extract) on dithranol-induced skin dam...
